I have to say the R90 racebike box is fine as I only change up on redline 7500 and down with a blip on the throttle.the big improvement was made in 1981 when they ditched the heavy flywheel and improved the clutch actuator.
Maxheadroom's R90s is really nice to ride as he has improved the gearbox ......for starters it has a small bearing instead of a nylon selector thingy... and some polished bits.
As BOB's said try matching the speeds of the engine with the box for smoother shifts.
